For convenient reference and aid in visual identification, this brochure showsthe most popular Holophane Controlens fluorescent lenses, with basic specifyinginformation. All Holophane lenses are injection-molded acrylic constructionfor unmatched optical prccision and clarity, as well as excellent color and me-chanical stability. Thcy will ensure uncompromised appearance and light controlefficiency for any luminaire.

Designerlenses.The 1/8?i -base cone prism 6244 Iens, pictured, is identical inappearance to lenses 6245, 622'7, 6228 and 6339. Lenses6251 and 62RF51 have a3/16t'prism cone base but other-wise look the same.Tapered rcinforcing ribs on the top of the 6250 lens dividethe lens into 1/xl/ segments, and add breakage resistancewhile providing a novel visual pattern.The revolutionary, unique 8224 Refractive Grid" lens fea-turcs excellent light utilization for wide spacing ratios,coupled with dramatic reduction of high angle brightness- lp to10% over the best cone prism lenses.The 7170 and'72'70 Perm-Align" is a dropped prismaticsidewall lens with an uplight component to reduce ceiling/luminaire contrast. It combines the efficiency of a cone prisrnwith the look of a dropped white diffuser.Regressed 7150 and 7250 lenses feature a 3/4'l sloped side-wall that creates a soft luminous transition between the lenssurface and ceiling.xx8xpxsppxsxpxxx x'xxptrrrppppxx*

Wraparound lenses.Injection-molded Holophane wrap-around lenses are both efficient andtough. With their rcsilient. integral whiteend caps, they form a unit that is ex-ceptionally resistant to breakage.
